Contrast in light intensity, rather than day length, influences the behavior and health of broiler chickens.
Day length and intensity are commonly manipulated aspects of the light environment in commercial broiler production. Both influence circadian rhythms, but it is unclear if they do this independently or synergistically. The effect of light:dark (20L:4D, 16L:8D) and intensity contrasts (1 lx:0.5 lx, 200 lx:0.5 lx) on broiler behavior and health (n=1,004, 4 replicates/treatment) was evaluated. Act...
متن کاملEstimation of Effective Day Length at Any Light Intensity Using Solar Radiation Data
The influence of day length on living creatures differs with the photosensitivity of the creature; however, the possible sunshine duration (N(0)) might be an inadequate index of the photoperiod for creatures with low light sensitivity. To address this issue, the authors tried to estimate the effective day length, i.e., the duration of the photoperiod that exceeds a certain threshold of light in...
متن کاملLight Requirement for the Carotenoids Production by Mucor hiemalis
Objective Fungi produce many different carotenoids and some are attractive in medical and industrial sources. In this work the ability of Mucor hiemalis (PTCC 5292) to produce carotenoids in media with different nitrogenous and carbon sources and incubation with white, yellow, blue and red lights (15W, 220V, E27) against dark-grown were studied. Materials and Method The microorganism cultiva...
متن کاملEffects of light intensity from photostimulation in four strains of commercial egg layers: 2. Egg production parameters.
The effects of light intensity (LI) from photostimulation to 45 wk of age on egg production parameters and egg size characteristics were examined in four layer strains. Floor housed pullets were raised in a light-tight facility from 1 d of age until housing in individually illuminated cages at 17 wk of age. At 17 wk of age, two white egg strains, ISA-White (ISA-W) and Shaver 2000 (S2000), and t...
